In the 18+ months since I stepped back into the world of geospatial consulting and services, one of the most striking things I have noticed is the seemingly increased tribalism in the geospatial space. Maybe I shouldn’t be surprised, given the increased tribalism of society in general, but that’s a different post that won’t get … Continue reading Walls and Bridges

Just Enough Geospatial
As I mentioned earlier this year, I spend a lot of time working in Python these days. More and more, my work seems to be about performing geospatial tasks with the minimal amount of geospatial dependencies possible. My most recent work has been generating contours from a set of sampled elevation points. I’ve done this … Continue reading Just Enough Geospatial
Producing GeoJSON with SQL
A couple of weeks ago, I had a need to return GeoJSON from PostGIS. This is something I've done many times, but I usually do the final formatting in the application/API layer with Javascript or Python. Basically, my workflow has been to SELECT, using the built-in ST_AsGeoJSON function to convert the geometry to GeoJSON. I … Continue reading Producing GeoJSON with SQL
Simple Geocoding with ChatGPT
Early in my career, I dealt with a requirement to post-process a corpus of existing documents to "geocode" them. This meant identifying the locations referenced in each document, calculating a minimum bounding rectangle (MBR), and writing the MBR, the file path, and some associated ID into a database, so that documents could be surfaced via … Continue reading Simple Geocoding with ChatGPT
Decoupling Maps
A couple of weeks ago, I took part in a live discussion of the Geospatial Innovations group on LinkedIn, along with Linda, Bonny, Tim, and Will. The topic was “Reimagining Maps” and was spurred by a couple of recent posts by Linda and Will - "Modern Mapping" and "Modern Geospatial", respectively. The discussion ostensibly examined … Continue reading Decoupling Maps
Rings In a Tree
As I was building a Python notebook in Databricks, I started thinking about how much Python work I've been doing since I went out on my own. That got me thinking about all of the SQL I had been doing the last couple of years at my previous role, then the Javascript before that and … Continue reading Rings In a Tree
In HIFLD, a Lesson
I spent the past couple of days at the Esri Federal GIS Conference, still referred to by many as the “FedUC,” in Washington, DC. The primary reason I went was to attend some customer meetings. The FedUC draws many people (6,000 in this year’s case) from around the country and it’s a convenient place to … Continue reading In HIFLD, a Lesson
Simpler Goals
I’m not a big fan of New Year’s resolutions. They are usually motivated by well-intentioned, but often misguided, factors and are typically designed to fail. That said, the annual passage of January 1 is a good milestone for assessing goals for the coming year. A lot of the work winds down between mid-December and January … Continue reading Simpler Goals
The One About Friends
I was having a conversation a few weeks ago, discussing, among other things, the value of time - its management, its conservation, how it is the one strategic asset that matters above all others. During that part of the conversation, it occurred to me that if time is the asset, then people and relationships are … Continue reading The One About Friends
Using pg_webhooks with n8n – A Simple Example
I've been integrating pg_webhooks into some project work lately. Conversely, I have not been using n8n much, but a vendor rep used it in a demo of some workflow automation capabilities for a platform one of my customers is using. I had dabbled with it about two years ago but haven't done much with it … Continue reading Using pg_webhooks with n8n – A Simple Example
